REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4350 Currently, stack HOB is not created for the stack memory. This causes stack memory to be treated as free memory and any memory allocation which happens at this address causes random memory corruption. Fix this by creating the stack HOB which marks the memory as BS data.
